The maint branch is regularly merged into the master and next branches, so it's there today. The maint branch will very shortly be the source of a 1.42.10 maintenance release. The master branch will eventualy be a 1.43 release; it has some much more disruptive changes, and adds support for metadata checksums, inline data, etc. It's likely that 1.42.10 will be the last maintenance release, and the focus will be on stablizing 1.43 and making sure we're really ready to support the ABI's for the new library functions in libext2fs to support these new features _forever_.
